Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a silver halide photographic light-sensitive material, and specifically relates to improvement of pasting marks.

[Background of the invention]

In recent years, in order to save labor, rationalize, and improve the working environment in the printing and plate-making field, there has been a demand for technology that allows film making, the so-called film-returning process, which was traditionally carried out in a dark room, to be carried out in a bright room. Improvements have been made to materials and equipment such as printers. Photosensitive materials that can be handled in a bright room (hereinafter simply referred to as bright room photosensitive materials) include halogenated materials that are primarily sensitive to light sources rich in ultraviolet light, such as ultra-high pressure mercury lamps, metal halide light sources, xenon lamps, and halogen lamps. Examples include silver photographic materials. These silver halide photographic light-sensitive materials can be handled under a bright general fluorescent lamp of +00 to 300 lux or a special fluorescent lamp with a low amount of ultraviolet rays. However, these bright room photosensitive materials have the following problems as compared to conventional photosensitive materials that are handled in a dark room. In other words, line drawing performance (cutting character performance) is poor when exposing halftone dot images and line images overlappingly as a returned original, and when line drawing originals and halftone originals are pasted and fixed on the base with transparent plate-making tape. Tape marks (attached tape marks)
This has the disadvantage that it leaves behind and spoils the finished image.

[Purpose of the invention]

In order to solve the above-mentioned problems of light-sensitive materials, the purpose of the present invention is to provide good performance when exposed to light from a selected light source, in particular, good photographic performance, with good cutout character quality in return characteristics, and to avoid tape pasting marks. An object of the present invention is to provide a silver halide photographic material.

[Structure of the invention]

The above object of the present invention is achieved by a silver halide photographic material characterized by containing a solid fine particle dispersion represented by the general formula [■].

Furthermore, it is desirable that the silver halide photographic material of the present invention contains a drazine compound or a tetrazolium compound.

Hereinafter, the present invention will be explained in detail.

The method of using a solid fine particle dispersion that absorbs in the ultraviolet region (hereinafter simply referred to as LJV agent) used in the present invention is a method in which a commonly used ultraviolet absorber is dissolved in water or an organic solvent and incorporated into a binder. Essentially different from this, we use a dispersion in which a type of ultraviolet absorber that is essentially insoluble in water at pH 6 or below is added to an aqueous solution or gelatin solution and made into fine particles in a ball mill or sand mill. be. The object of the present invention is to fix the solid fine particle dispersion thus dispersed in a certain layer of a silver halide photographic light-sensitive material.

The solid fine particle dispersion obtained by the above method acts effectively during image formation and improves the quality of blank characters and pasting.

An electrodeless discharge tube light source (manufactured by SION) was attached below the glass plate, and the original and the photosensitive material were exposed in an overlapping manner so that the quality of pasting marks and cut-out characters as shown in FIG. 2 could be evaluated on the glass surface.

Photographic performance evaluation method (1) At the pasting mark in Figure 2, place the mesh film 2 on the pasting base 3.5, and further fix the periphery of the mesh film with transparent scotch tape for plate making. When there was no tape mark (pasting mark) after the exposure and development process, a rating of "5" was given, with the worst level being rlJ, where the mark was conspicuous and the worst level was rated on a five-point scale.

(2) Cutout character quality The cutout character quality is 50% of the mesh film 2 in Figure 2.
The reproduced image quality is the line width of 50 μm on the line drawing film 4 in FIG. A five-point evaluation was made, with very good cutout character image quality being rated "5" and the worst being N and +.

The results are shown in Table 1.

[Effects of the Invention] It can be seen that the silver halide photographic material provided with the layer containing the solid fine particle dispersion of the ultraviolet absorber of the present invention is superior after lamination. It is also found that when a tetrazolium compound or a hydrazine compound is contained, the pasting mark and cutout character quality are even better.
